Melonex Proprietary Blend: What the Rule Allows and What Is Hidden
Melonex lists one Proprietary Blend of 500 mg per capsule, naming three amino acid forms with no individual amounts. Federal labeling rules allow that, as long as the names run in descending order by weight. So you can learn the order, but never the exact milligrams of each.

What does the rule allow?
A label may group ingredients under a blend name, list them in descending order by weight and show only the blend total 1.
The total is 500 mg, and the Daily Value is "not established". Individual amounts are not required. That is lawful. It is also why the label reads the way it does, with names and no numbers. A shopper learns the order and the total, and little else.

See packsHow wide are the possible ranges?
Wide enough that two capsules with the same label could hold quite different mixes.

Bars show the widest range the label order allows for each name 1. The real split is not printed.
FDA says blend members are exempt from per-ingredient amounts 2. See the blend page for the long version. In plain terms, one capsule could lean heavily on the first name and hold very little of the other two, or spread more evenly. The printed order cannot tell those apart.
What can you ask the seller?
Ask for the amount of each name per capsule and for a lab report for your lot.
- What are the milligrams of each of the three names?
- Which lab tested my lot, and can I see the report?
- Was the finished capsule tested in people?
Seller references such as a lot number are not proof of anything on their own. Get answers in writing, then decide. The Supplement Facts page and the ingredients page hold the rest. If no one can give the amounts, you are paying for a total weight and three names. That may be fine for you, but it should be a choice you make with your eyes open, and with your pharmacist told about every ingredient.
